Figure 4. Evidence for value-based attention.

Figure 4

a Path analysis testing a mediation of the distractor effect by attention. As predicted, distractor value was positively linked to relative gaze duration on the distractor. Due to the absence of a distractor effect on relative choice accuracy, however, there was no mediation. b The probability to fixate different option types at the first fixation was not random. Individual data points (gray dots) are shown together with group means (colored lines) and 95% CIs (black error bars). The effect remains significant when excluding the outlier with 58% / 10% first fixations on the best option / the distractor. c Development of fixations per option type over the course of single trials. d Development of fixations on high- and low-value distractors over the course of single trials. Consistent with value-based attention, the decline of fixation probability is modulated by distractor value. *p < .05, ***p < .001
